See full text

For regenerating the sand, which is obtained from sand molds and/or sand cores, which are produced from the sand and soluble glass as a binder and are used in metal casting, the sand obtained from the sand molds and/or sand cores is subjected to a mechanical regeneration stage and a thermal regeneration stage. During or after the mechanical regeneration stage, the obtained sand is mixed with a hardener for soluble glass.
